Hello,
Anybody know how to tell the date of manufacture on the tubes of WN gouache? I came into some tubes, about 40 that are “new” but have been in a drawer for a number of years.
The tubes have 4 numbers printed in black @ the bottom, like ‘0934’, ‘5262’, etc
And, if I was going to try to prevent said tubes from doing whatever WN gouache does maybe 5-15 years after manufacture, what would that be? Vacuum seal in a Food Saver system, or put in the frig, or both?
I can list the 7-10 colors if that would be helpful
Thanks to all,
David
